Omega 3 Supplements: Which One to Take? Featured

(HealthCastle.com) If you have been instructed by your doctor to take omega-3 fatty acid supplements for your heart condition, you might have experienced some confusion and frustration at the store shelf. From the simple "Omega-3" to "Pharmaceutical Grade Wild Salmon Fish Oil Complex," there is a plethora of choices out there. Be confused no more - let us help you navigate the zoo and find the right omega-3 fatty acid supplement for you.

What You Need to Look For

The name of the supplement may not necessarily tell you anything. The first rule of thumb is to check the ingredients. You need to look for DHA (Docosahexaenoic acid) and/or EPA (Eicosapentaenoic acid), the two long-chain omega-3 fatty acids that have been shown to be helpful in the prevention of heart diseases. Depending on the dose your doctor prescribed, you can then determine which supplement will give you enough, without needing to take too many capsules each day.

Omega-3 or Omega 3-6-9?

The more types of omegas, the better? The answer is no. Although both omega-3 and omega-6 fatty acids are essential (meaning that your body cannot synthesize them from scratch), the typical American diet is very high in omega-6 and deficient in omega-3 fats. Omega-9 fatty acids, which are monounsaturated fatty acids (e.g., oleic acid, a fatty acid found in olive oil), offer many health benefits, but humans can synthesize them from other fatty acids. So forget about the omega-6 and omega-9, and simply focus on what you need, i.e., an omega-3 fatty acid supplement that is rich in DHA and EPA for maximum health benefits.

Source of the Omega-3 Fatty Acids

Fish oil: This is one of the best sources of DHA and EPA. The levels and quality of these oils may vary due to different sources and methods of processing. According to a ConsumerLab report, all of the supplements (including algal and krill oils) contain extremely low levels of PCBs, but no detectable levels of mercury or unsafe levels of lead. To minimize contaminants, it is best to choose supplements made from smaller fish that are lower in the food chain (such as anchovies, sardines, and menhaden).

Algal oil: Algae are also a source of EPA and DHA. As they are very low on the food chain, algal oils are typically lower in contaminants. Algal oil tends to be more expensive, but would be a good option if you are looking for a vegetarian supplement.

Krill oil: Like fish, krill (a shrimp-like crustacean) is also a good source of DHA and EPA. However, since krill is a primary food source for certain whales, penguins, and other marine animals, harvesting krill has generated some controversy.

Fish liver oil (e.g., cod liver oil and halibut liver oil): Although fish liver oils are a source of omega-3 fatty acids, because of their high levels of Vitamins A and Vitamins D , they may cause toxicity if taken in excessive amounts. Fish liver oil is therefore not a recommended type of supplement.

Flax oil: The main type of omega-3 fatty acid in flax is ALA (alpha-linolenic acid), which is a shorter-chain omega-3 fatty acid. While technically your body can manufacture EPA and DHA from ALA, the conversion is unfortunately rather limited. If you need to take a supplement, you are probably better off taking one that actually contains EPA and DHA, like fish or algal oil.

The Bottom Line

When it comes to picking a quality omega-3 fatty acid supplement, price isn't always a good indicator. If you are not vegetarian, choose a supplement that is sourced from small oily fish and contains adequate amounts of DHA and EPA (as prescribed by your physician). If you dislike the fishy burps, choosing enteric-coated pills over softgels may offer some relief. Pay no attention to claims such as "pharmaceutical grade," as they don't mean much.
